f 7 Claims.

This invention relates to improvements in pens, and more particularly toa magazine pen providing a plurality of pens in one barrel whereby anumber of different colored inks are available.'

An object of the present invention is toprovide a plurality of fountainpens within a common barrel, each movable by rotation of the pen unit toan ejecting position where it coacts with an actuator on the barrel bywhich the selected pen is moved out of the barrel to writing position.

Our invention includes a novel and simple frame structure for supportinga plurality of pens for rotation within a barrel and for movement of aselected one of said pens out of the barrel to writing position.

Another feature of our invention is the arrangement of a plurality of"reflllable Afountain pens within a common barrel each selectivelymovable to a position for ejection to writing position and each rellableby manipulation of an actuator on the barrel when in said writingposition.

Another feature of our invention is the arrangement of three cylindricalfountain pens within a cylindrical barrel which permits each pen to havea diameter substantially equal to the inside radius I of the barrel. y

Other novel features of pen construction will i be apparent from theaccompanying drawing and description and the essential features will besummarized inthe claims.

In the drawing, Fig. 1 is an elevational view of our novel pen with aportion of the cap broken away; Fig. 2 is a central longitudinal sectionthrough the pen of Fig. 1 with the cap removed and a pen in writingposition; Figs. 3 and 4 are transverse sections taken along similarlynum' bered lines of Fig. 2; Fig. 5 is an end view of the pen of Figs. 1and 2 with the cap removed and all pens in retracted position; whileFig. 6 is a perspective view of the pen carrying frame which in use ishoused in the pen barrel'.

While our invention may be applied to a magazine pen having a varyingnumber of pens therein, the preferred form is illustrated herewith andcomprises three fountain pens I housed within a casing or barrel I I andselectively movable into and out of writing position as desired.

The frame l2 which carries the pens I0 is most clearly shown in Fig. 6.It comprises a plurality of transverse membersincluding the base memberI3 and spaced therefrom the members I4 and I5, these latter two beingnotched to receive the' pens I0. Three longitudinally extending rods I6help to rigidly secure the transversemembers in place and serve asguides for the pens I0 during their sliding movement as will laterappear. A central rod Il also serves as a rigidifying portionlof theframe and aids in the positioning of the pens. The base portion I3 issupplied with a cap I3a rigid therewith extending at the rear end of thebarrel and serving for manipulationof the frame I2. The base portion I3carries a plurality of spring pressed detents I8 which when the pen isassembled register with holes I9 in the barrel and hold the frame in anyof its adjusted positions.

Each pen Il) comprises a cylindrical shell or other vsuitable framework20 carrying at one end a pen point 2l which communicates with a ilexibleink sack or reservoir 22 preferably of rubber. Each of the pen cylindershas a slot 23 facing outwardly for coaction with a traveling actuator bywhich the pens are moved longitudinally of the barrel. Each of thecylinders 20 also carries a flexible spring metal piece 24' overlying aslot 4in the cylinder wall, this being a usual construction by which thespring member is arranged to press inwardly upon the flexible reservoir22 expelling the air from the reservoir and upon re-expansion of thereservoir it islled with ink through the point 2| in the well knownmanner.

p At its rear end each pen has a plate 25 rigid therewith and having anopening 25a which engages one of the rods I6 so that the pen rotateswith the frame I2 but is slidabl along its assoc iated rod I6. Thisconstruction is shown in Fig. 3 where two of the pens are in theirretracted position and the thirdv pen is advanced to writingV position,but its place when retracted is indicated in dot-dash lines.

On the barrel II is slidably mounted an actuator 26 for advancing andretracting each pen selectively out of and into the barrel. Thisactuatoi` has a portion 26a which enters a guideway2l on the barrel toguide the reciprocation of the actuator. It also carries a pin 26h whichis adapted to engage the slot 23 in a selected pen so that the actuatormay move the pen out of the barrel to writing position. The slots 23when the pens are all in retracted position are alined with the pin 2Gbwhen the latter is in its retracted position as shown in Fig. 1. Inother positions of the actuator or pens, the pin 2Gb will engage the.pen cylinders 20 and prevent their rotation within the barrel. Theactuator also has a spring pressed detent 26o vwhich is adapted to entera recess 28 in the pen barrel, thus holding any selected pen in itsadvanced or writing position. y v On the forward part of the barrel is asecond actuator 29 pivotally mounted on the barrel at 30 and having anend 29a adapted to engage one of the springs 24 when a pen is in writingposition and the actuator is moved to the broken line position of Fig.2. This collapses the ink reservoir 22 for a, pen refilling operation.Thus one actuator serves to rell a plurality of pens.

The barrel is closed at its rear end by the base portion I3 and the capportion I3a of the frame I2. This cap portion may be supplied withmarkers 3I of a color corresponding to the inks in the associated pens,this marker movingto an indicating position as in Fig. l-when itsassociated pen is in position for advancement out of the barrel, whichposition is indicated by a detent I8 The other end of entering one ofthe holes I9. the barrel is closed by a molded plastic compositionmember 32 which is circular inelevation as shown in Fig. 5, except forthe opening 32a which corresponds to the outside diameter of a pencylinder 20 and permits the ejecting movement of a selected pen at thispoint. A closing cap 33 is provided at the leading end of the barrel andmay be secured to the pen in any suitable manner, the form showncomprising a threaded member 34 carried by the molded member 32. Thismolded member also has. a recess 3211 into which the, end of the rod I1of the frame enters.

- In use, the cap 33 is rst removed and the end piece I3a -is rotateduntil the Vmarker 3| registers with the arrow on top of the barrel as inFig. 1, indicating that the pen-carrying theproper color ink is inregistering position with the opening 32a.

lIYhis rotation of the frame I2 by the end piece I3ais as previouslymentioned only possible when the actuator 26 is in its rearmost positionas shown in Fig. l.` With the proper pen so .selected actuator 26 `ismoved forwardlyand bythe coaction of pin 26h in slot 23 moves theselected pen out of the barrel to writing position as shown in Fig. 2.When any pen is thus ,in writing position, actuator 29 may bemanipulated to refill the pen as already described. When finished with apen, the actuator 26 is retracted moving the pen again into the barrel,whereupon another pen may be moved to writing position in the same wayif desired.
